Phonics breakdown
Phonics Rule: TH Digraph (Unvoiced)
TH can make a soft sound /θ/, like in 'think' and 'bath'. Just air, no buzz!
The unvoiced TH /θ/ is the quiet, breathy version. Your throat doesn't vibrate. Stick your tongue between your teeth and blow air.
Tip
Unvoiced TH is quiet — think with three teeth!
Examples
Phonics Rule: R-Controlled IR
When R comes after I, it makes the /ɜːr/ sound, like in 'bird' and 'first'.
IR makes the same /ɜːr/ sound as ER and UR. There's no difference in pronunciation — only in spelling.
Tip
The bird in a shirt says /ɜːr/!
Examples
Phonics Rule: Letter T
The letter T makes the /t/ sound, like in 'top', 'tap', and 'ten'. The tongue tip taps behind the upper teeth.
T is a voiceless alveolar stop. The tongue tip touches the ridge behind the upper teeth and releases with a puff of air. Double T (tt) makes the same /t/ sound.
Tip
T taps — touch your tongue to make /t/!
Examples
Phonics Rule: EE Vowel Team
When two E's are together, they say long E, like in 'tree' and 'see'.
The vowel team 'ee' almost always makes the long E sound /iː/. This is one of the most reliable vowel teams in English.
Tip
Two E's together always agree — they say /iː/!
Examples
Phonics Rule: Letter N
The letter N makes the /n/ sound, like in 'net', 'nap', and 'nut'. The tongue tip touches behind the upper teeth.
N is a voiced alveolar nasal — the tongue tip touches the ridge behind the upper teeth while voice hums through the nose. It is one of the most common consonants in English.
Tip
N hums through the nose — say /n/ and feel the buzz!
